Picked up a drop test kit from walmart today did the test and every thing is fine except the alk. I tested 3 times, and have been getting a steady 310 - 320 alk reading with a ph of 7.3. Can this be right or do I need to return the test strips. all the reading that I've doing reguarding ph and alk indicates a close relationship between the two, so how would it get so out of whack? According to test strips I've been uusing in the past, it always registered in the 160 - 180 range, with ph at 7.0. Another concern is the chlorine test is total chlorine, and doesn't differentiate between free or combined, so I'll have to rely on strips for that. also, does anyone know where I can get replacement regeant solution for the cya test? With the amount they have you use, I'll have maybe enough for 3 more tests for that if I'm lucky.
